Fast delivery from stock
All standard dimensions of glass melting electrodes are available directly from stock via PLANSEE Express. The diameters from
the list below are all delivered in our special smooth-forged surface-quality with stated straightness. Metric, tapered or customerspecific
threadings are available in two to three weeks. The table below shows the recommended standardized metric and tapered
threads for the respective electrode diameters in order to guarantee optimal mechanical and electrical properties when in use.
